Links to find work by photographers

I read the FAQ and understand the site policy on why there isn't a gallery for your photo resources. However, I was wondering if it where possible to get a credits page? Some of the photographs I've found to be incredibly captivating and would like to do more research into the artist that created them.
Also, it would be nice to be able to have access to the photographs in the collection that are part of public domain. I fell in love with the work of Julian Mandel by using this site. When I went to do more research on him I quickly found this site has one of the best archives of his work. With him being dead for more than 80 years now, the vast majority of his work has to be in public domain. I don't understand the conflict of creating a gallery for his work and others that belong to the public.
